Rev.04.10.12 1.0 DS2900-3 Series Page 1 DS2900 2900 Watts Distributed Power System Total Power: 2900 Watts Input Voltage: 180-264 Vac of Outputs: Main + standby Special Features Active power factor correction EN61000-3-2 harmonic compliance Active AC inrush control 2U X 3U form factor Product Descriptions 3 24.8 W / in +12 Vdc Output The DS2900 power supply features a very wide 180V to 264 Vac input voltage +3.3 Vdc stand-by range and employ active power factor correction to minimize input harmonic (5 V standby - consult factory) current distortion and to ensure compliance with the international EN61000-3-2 No minimum load required standard they have a power factor of 0.99 typical. The power supplies also Hot plug operation feature active ac inrush control, to automatically limit inrush current at turn-on to N + 1 redundant 50 A maximum, and is protected against overvoltage conditions up to 130 Internal ORing fets percent. Active current sharing The power supply employs a new patent-pending ultra high efficiency conversion (10 - 100% load) 2 topology, together with an innovative power transformer and rectifier construction I C communication interface bus that further improves power density and reduces interconnect power losses. The PMBus compliant power supplys main +12 Vdc payload output is digitally programmable over the EERPOM for FRU data 2 range 11.52 to 12.48Vdc, and users have a choice of standard I C or advanced 2 LED (Green and Amber) PMBus communications. The control software runs under Windows on any Internal fan speed control standard PC, and uses a highly intuitive graphical user interface to simplify INTEL, SSI Std. logic timing power supply set-up. INTEL, SSI Std. FRU data format Full digital control The DS2900 can deliver up to 240 A from its main +12 Vdc payload output, and Two year warranty up to 3A from its +3.3 Vdc auxiliary output. The supply has a 2U x 3U form factor and has a power density of more than 24.8 watts per cubic inch. The Safety DS2900 can achieve a very high 91 percent typical conversion efficiency at 50 percent load.
